Method and Device for Encoding/Decoding Image Using Geometrically Modified Picture

2. The method of claim 1, wherein the geometric modification information is reconfigured by simplifying or predicting the geometric modification information.

3. The method of claim 1, wherein the geometric modification information is generated based on a change in pixel information between a current picture including the current block and the reference picture.

4. The method of claim 3, wherein the geometric modification information is generated based on matching information between feature points that are extracted from each of the current picture and the reference picture.

6. The method of claim 5, wherein when the point corresponding to the point within the geometric modified picture is not present within the reference picture, a point closest to the corresponding point within the reference picture is identified as the corresponding point.

9. The method of claim 8, wherein when the point corresponding to the point within the geometric modified picture is not present within the reference picture, a point closest to the corresponding point within the reference picture is identified as the corresponding point.

10. The method of claim 8, wherein when the corresponding point within the reference picture has a real number coordinate, one or more points each having an integer number coordinate and neighboring to the corresponding point within the reference picture is identified, and pixel information of the corresponding point within the reference picture is derived based on pixel information of the one or more points each having the integer number coordinate.

11. The method of claim 7, wherein the generating the geometric modified picture is performed in at least one unit of a picture, a tile, a coding unit, and a prediction unit.
